prerogative: [14] Latin praerogāre meant ‘ask before others’ (it was a compound verb formed from the prefix prae- ‘before’ and rogāre ‘ask’, source also of English interrogate [15]). The term praerogātīva (based on its past participle) was applied to those electoral groups who were ‘invited before others’ to vote, or in other words had the privilege of voting first, in elections for state officials. Hence the word (acquired by English via Old French prerogative) came to mean in general ‘right to precedence, privilege’.
